Embodiment 1
[0421] (Manufacture of Exemplary Compound 1)
[0422] Exemplified Compound 1 was produced according to the following scheme.
[0423] At room temperature, to 2.5 g of 3-methyl-2-(2-N-acetylanilinovinyl) benzoxazolium iodide, 1.4 g of cyanoacetic acid 2-methacryloyloxyethyl A mixture of ester, 6 mL (milliliters) of acetonitrile was added with 0.7 g of triethylamine. The reaction mixture was stirred at room temperature for 3 hours, and 6 mL of ion-exchanged water was added. After stirring for 1 hour, the precipitated crystals were collected by filtration, and washed with a mixed solution of acetonitrile / ion-exchanged water=1 / 1 (vol). 18 mL of isopropanol was added to the obtained crystals, followed by heating to reflux. After the mixture was cooled to room temperature, it was filtered and dried to obtain 1.7 g of Exemplified Compound 1.
[0424] In addition, the room temperature in the synthesis of the exemplified compounds refers to "room temperature not particularly contro...
Embodiment 2
[0434] (Manufacture of Exemplary Compound 9)
[0435] Exemplified compound 9 was produced according to the following scheme.
[0436] At room temperature, to 2.9 g of 3-methyl-2-(2-N-acetylanilinovinyl) benzoxazolium iodide, 1.6 g of 2-methacryloyloxyethyl acetoacetate , 7 mL of acetonitrile was added to a mixture of 0.8 g of triethylamine. The reaction mixture was stirred at room temperature for 3 hours, and 7 mL of ion-exchanged water was added. After stirring for 1 hour, the precipitated crystals were collected by filtration, and washed with a mixed solution of acetonitrile / ion-exchanged water=1 / 1 (vol). The obtained crystals were recrystallized from 14 mL of isopropanol to obtain 1.4 g of Exemplified Compound 9 as a mixture of geometric isomers.
[0437] [chemical formula 20]
[0438]
[0439] The analysis results by NMR of Exemplary Compound 9, the maximum absorption wavelength (denoted as λmax) measured by the above method, and the ratio of the absorption at a wav...
Embodiment 3
[0445] (Manufacture of Exemplary Compound 31)
[0446] Exemplified compound 31 was produced according to the following scheme.
[0447] At room temperature, to 3.0 g of 3-ethyl-2-(2-N-acetylanilinovinyl) benzoxazolium iodide, 2.4 g of 2-[2-(phenylsulfonyl) acetyl 0.8 g of triethylamine was added to a mixture of oxy]ethyl methacrylate, 7 mL of acetonitrile. The reaction mixture was stirred at room temperature for 12 hours, and 10.5 mL of ion-exchanged water was added. The precipitated crystals were collected by filtration and washed with ion-exchanged water. The obtained crystals were recrystallized from 7 mL of acetonitrile to obtain 1.8 g of Exemplified Compound 31.
[0448] [chemical formula 21]
[0449]
[0450] The analysis results by NMR of Exemplary Compound 31, the maximum absorption wavelength (denoted as λmax) measured by the above method, and the ratio of the absorption at a wavelength of 440 nm to the absorption at a wavelength of 405 nm are shown below.
